Abstract

The histones of the endosymbiont nucleus of the binucleate dinoflagellate Peridinium balticum were characterized by amino acid analysis and peptide mapping, and compared to calf thymus histones. Using these and various other criteria we have identified two H1-like histones as well as the highly conserved histones H3 and H4. A 13,000 dalton component in sodium dodecyl sulphate (SDS) gels can be separated into two components in Triton-containing gels. We suggest that these histones (HPb1 and HPb2) correspond to the vertebrate histones H2A and H2B, respectively.

摘要

通过氨基酸分析和肽图谱对双核甲藻波罗的海多甲藻内共生细胞核的组蛋白进行了表征，并与小牛胸腺组蛋白进行了比较。利用这些以及各种其他标准，我们鉴定出了两种H1样组蛋白以及高度保守的组蛋白H3和H4。十二烷基硫酸钠（SDS）凝胶中的一种13,000道尔顿的成分在含 Triton 的凝胶中可分离成两种成分。我们认为这些组蛋白（HPb1和HPb2）分别对应于脊椎动物的组蛋白H2A和H2B。
